Power on with Australian designed and fabricated kiosk substations.

2 CUSTOMER SERVICE: 1300 736 318

Switch on with Mayfield for total kiosk substation confidence.

For decades, Mayfield’s modular kiosk substations have unfailingly delivered for Australian mining, utilities and heavy industries in the most demanding environments.

Our proven designs, materials and specifications prevent wind driven water ingress, minimise dust entry and ensure sufficient airflow for extreme ambient temperatures – all combining to deliver optimal protection for critical electrical equipment. Whether using our kiosk substations for short term emergency response or a long term fix to existing plant, customers can be certain their critical upstream and downstream electrical equipment will be protected and safe.

We provide turnkey solutions incorporating LV and MV switchboards, with all equipment installed in our manufacturing facilities and extensively tested before deployment to site, reducing on-site disruption and costs. The modular construction of our kiosk substations ensures segregation of equipment and allows for flexibility in sizing, layout, application, inspection and maintenance.

At Mayfield, we welcome tight deadlines. Our end-to-end manufacturing and installation allows us to maintain total control over quality while eliminating the delays that come with outsourcing to others.

The standard Mayfield modular kiosk substations includes:

• Ingress protection ≤IP66• Natural and Mechanical ventilation solutions • Detailed design and fabrication • MV switchgear (RMU and Transformer)• LV switchboards • Cabling between MV/TX/LV• Pre-commissioning and testing completed before factory dispatch.

Additional options include:

• Interconnecting cabling• Internal/external power and lighting• Transportation of kiosk to site• Site installation and

commissioning.

STANDARD FEATURES

Features include:

Modular construction, allowing design and specification flexibility; each compartment can be sized to accommodate the specific equipment.

Removable wall and roof panels, providing:• Easy access to critical equipment

for maintenance• An internal structural framework

for rigidity and easy cladding attachment

• Transformer oil bund containment, avoiding the need for additional site works.

External walls and roof

The internal structural frame is manufactured from 2mm sheet steel.

Walls, roofing and doors are manufactured from 2mm sheet steel.

Marine-grade aluminium or stainless steel is also available as an option.

Doors

Doors are designed and sized for easy passage and installation of electrical equipment. Stainless steel hinges, latches and locks are available as an option.
